In this state, as shown in FIG. 3, the telephone line 4 may be held between the horizontal piece of the tension stopper 9 and the bottom surface of the recessed groove, or the telephone line 4 may be entwined around the tension stop member 9. This prevents the tension acting on the telephone line 4 from being transmitted to the connection portion with the terminal 5.

(Embodiment 2) In the embodiment shown in FIG. 4, the tension stop member 9a is integrally provided to protrude from the center of the bottom of the groove 7 provided on the rear surface of the casing 1. 1, the telephone line 4 is held between the horizontal piece of the tension stopper 9a and the bottom surface of the groove 7, or alternatively, the telephone line 4 is held between the tension stop member 9a
By entangling the telephone line 4 with the terminal 5, the tension acting on the telephone line 4 is prevented from being transmitted to the connection portion with the terminal 5.

(Embodiment 3) In the embodiment shown in FIGS. 5 and 6, fitting recesses 21 are formed on both left and right side surfaces of the casing 1, and fitting pieces that can be fitted into both fitting recesses 21 are provided. A tension stop member 9b with 22 is provided. This tension stopper member 9b is formed along the shape of the rear surface of the casing 1, and when the tip of the fitting piece 22 is fitted into the fitting recess 21, as shown in FIG. In addition, the terminal 5 and the groove 7 are covered. Therefore, by attaching the tension stopper 9b to the casing 1 with the telephone line 4 connected to the terminal 5, the telephone line 4 can be held between the tension stopper 9b and the groove 7. This prevents the tension acting on the telephone line 4 from being transmitted to the connection portion with the terminal 5.

(Embodiment 4) In the embodiment shown in FIGS. 7 and 8, the tension stop member 9c
is composed of a pair of sandwiching plates 31 that sandwich the telephone line 4. A fitting recess 32 is formed at the base of the partition plate 6 that separates the terminals 5 from each other, and fitting protrusions 33 are formed in a protruding manner on the side surfaces of the base of both sandwiching plates 31. Therefore, in order to connect the telephone line 4, the telephone line 4 is sandwiched between the sandwiching plates 31, and the sandwiching plate 31 is press-fitted between the pair of partition plates 6 that separate the terminals 5 from each other. The fitting projections 33 of the partition plate 6 are fitted into the fitting recesses 32 of the partition plate 6, and the tension stopper member 9c is fixed to the casing 1. At the same time, the telephone line 4 is held between the clamping plates 31, and the telephone line 4 is held between the clamping plates 31. 4 is held between the sandwiching plate 31 and the bottom surface of the groove 7, the tension acting on the telephone line 4 is transferred to the terminal 5.
This prevents the transmission of the signal to the connecting part.

The telephone jack A constructed as described above is attached to a ready-made mounting frame 15, as shown in FIGS. 9 and 10. This mounting frame 15 allows three ready-made wiring molds to be mounted thereon, and is made of synthetic resin. The mounting frame 15 is a vertically elongated frame body, and the left and right widths of the opening 41 in the center are approximately equal in the left and right sides of the casing 1, and the vertical width of the opening 41 is equal to that of the casing 1. The width is approximately three times the width in the vertical direction.
